Thus* we tended to stick to the <br />higher areas while still leaving room for ample building <br />sites. However* cnee houses are proposed to be constructed <br />it might be desired to shift some of the drainfield areas. <br />Then n w testing would be required and it would be advise- <br />able to keep ls high up 0:1 the kntb? as was previously tes­ <br />ted. <br />Each site tested '.c.Tuld be acceptable for either a stcn* <br />dard or shallow trench drainfield system and is noted on the <br />attached drawing. It also night be necessary to use inter* <br />ceptor drains to divert runoff water but this would be men-' <br />ticned in the system design for the Individual houses once <br />they ere ready for construction. If any additional informa­ <br />tion is needed* please contact me. <br />Sincerely* <br />PERCOR* IKC. <br />“^Mark S. Gronberg*
